Steps to reproduce the problem

Given this deps.end:

;; deps.edn
{:deps {org.clojure/clojure {:mvn/version "1.12.0-alpha10"}
        org.clojure/tools.deps {:mvn/version "0.19.1421"}}}

1. (setq cider-enrich-classpath t)
2. M-x cider-jack-in
3. In the REPL (add-lib 'cheshire/cheshire {:mvn/version "5.13.0"})
4. error

To reproduce the successful behavior:

1. (setq cider-enrich-classpath nil) or run plain REPL with clojure
2. M-x cider-jack-in
3. In the REPL (add-lib 'cheshire/cheshire {:mvn/version "5.13.0"})
4. success

Note, Borkdude's deps.add-lib works when enrich-classpath is t

[vemv]

Thanks for the report!

It's a fairly baffling one since Enrich doesn't particularly add or modify Maven stuff. It doesn't add/run code either in your repl JVM.

It does all its work before the JVM is launched. It generates an 'enriched' classpath and then it's done.

Sadly, "Failed to read artifact descriptor for" is an uninformative error message, so you'd have to figure out the real cause.

I'd suggest:

• run a repl with Enrich enabled
• locate where com.fasterxml.jackson.core:jackson-core:jar:2.17.0 is in the classpath for that repl
• check if there's any reason for the artifact descriptor to be unreadable.

Cheers - V

I guess there are more problems than that. For instance, at work I regularly experience problems with downloading missing libraries through a proxy if I jack-in and some libraries are not present in the .m2. If I disable the cider-enrich-classpath feature, downloading works properly, and the REPL starts fine. (in this particular issue there's no proxy used)

So I guess maybe the problem lies with how the clojure.sh script that wraps the enrich classpath feature is run by Emacs.

[vemv]

It sounds like Enrich could observe some env vars for proxy stuff, feel free to ellaborate in https://github.com/clojure-emacs/enrich-classpath/issues

(Very commonly apps do that - AFAIK, we cannot guess if we need a proxy / which)

[andreyorst]

locate where com.fasterxml.jackson.core:jackson-core:jar:2.17.0 is in the classpath for that repl

I don't think it's located anywhere yet, as add-libs tries to download it, and fails to find the artifact. Maybe I'm wrong.

Can you elaborate a bit on the steps? I'm a bit lost with this maven stuff.

[vemv]

Hmm, if this stuff isn't too familiar it will probably be quicker if I give it a go.

Please report the proxy issue first, let's get it fixed and see if this one persists.

In the meantime you can disable Enrich (globally or in .dir-locals.el)

I went down this rabbit hole and I think the problem is related to how the clojure.sh script calls the clojure command who ends up calling clojure.tools.deps.script.make-classpath2 who will write down the .cpcache/xxxx.basis file which will be used by the tools.deps basis system then used by add-lib.

Here are the differences between how the Clojure script calls clojure.tools.deps.script.make-classpath2/-main vs the same when wrapped by enrich clojure.sh :

("--config-user" "/home/jmonetta/.clojure/deps.edn" "--config-project" "deps.edn" "--basis-file" ".cpcache/405540774.basis"  "--cp-file" ".cpcache/405540774.cp"  "--jvm-file" ".cpcache/405540774.jvm"  "--main-file" ".cpcache/405540774.main"  "--manifest-file" ".cpcache/405540774.manifest" "--config-data" "{:deps {nrepl/nrepl {:mvn/version \"1.1.1\"} cider/cider-nrepl {:mvn/version \"0.47.0\"} refactor-nrepl/refactor-nrepl {:mvn/version \"3.10.0\"}} :aliases {:cider/nrepl {:main-opts [\"-m\" \"nrepl.cmdline\" \"--middleware\" \"[refactor-nrepl.middleware/wrap-refactor,cider.nrepl/cider-middleware]\"]}}}" "-M:dev:cider/nrepl")
("--config-user" ""                                 "--config-project" "deps.edn" "--basis-file" ".cpcache/3864922009.basis" "--cp-file" ".cpcache/3864922009.cp" "--jvm-file" ".cpcache/3864922009.jvm" "--main-file" ".cpcache/3864922009.main" "--manifest-file" ".cpcache/3864922009.manifest" "--skip-cp")

I think the problem is the enrich system is not providing dependencies information to the clojure command since it is going to calculate the classpath itself, but this ends up in the .basis file being written with nil, which then breaks other tools.deps systems.

Also the config user folder looks empty.

[vemv]

Thanks much for the digging into the 🌀🐇!

In Alex words:

yeah, if using -Scp, you're basically turning off the whole "calculate deps and basis" system

Looks like Enrich could do some explicit effort at writing a valid .basis file (probably using the tools.deps API) and passing it as a System property (since I've observed that's what the Clojure CLI commonly does?)

Might be an easy addition.

The --config-user issue looks like a separate one. Might have to do with the tmpdir jumping.
